A Federal Police Black Hawk helicopter flies over the Tuxpan prison after a shooting in Iguala, in the Mexican State of Guerrero January 3, 2014. Nine people were killed during a gunfight at the prison in Mexico's violent Guerrero state, after a gang dressed as police officers gained entry on Friday, authorities said. Six gunmen wearing police uniforms were allowed to enter the prison by unsuspecting guards who believed the men were delivering another prisoner, state prosecutors said.
